Let's divide 12440534 by 813
Let's see how many times 813 fits into 12440534.

Let's proceed to step 1:
1 divided by 813 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 813

Going ahead to step 2:
If we divide 12 by 813, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 813

Step 3:
When dividing 124 by 813, we get 0 with a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Take the next digit (4) from the dividend and append it to 124, then repeat: 1244 / 813

Let's proceed to step 4:
813 goes into 1244 1 times with a remainder of 431.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 813 away from 1244, we end up with 431.
Append the next digit (0) from the dividend to 431 and continue with: 4310 / 813

Advancing to step 5:
813 can be fit into 4310 5 times, resulting in a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 4065 from 4310 leaves us with 245.
Take the next digit (5) from the dividend and append it to 245, then repeat: 2455 / 813

Going ahead to step 6:
If we divide 2455 by 813, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
If we take 2439 away from 2455, we end up with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 813

Going ahead to step 7:
813 goes into 163 0 times with a remainder of 163.
The number 0 becomes the next digit in our result. 
Result so far: 1530.0
Subtract 0 from 163 to get 163.
Bring next digit (4) of the dividend behind the 163 and repeat the process: 1634 / 813

Advancing to step 8:
If we divide 1634 by 813, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 15302.0
Subtracting 1626 from 1634 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
813 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 15302.0
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
The number 813 fits into 800 0 times, leaving a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 15302.0
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 15302.0 with a remaining 0.8.
